SECOND CLUSTER LAUNCH TO COMPLETE ON ORBIT QUARTET

     The two remaining Cluster spacecraft, set to launch next
week, will rendezvous in mid-August with their two sister ships,
creating a fleet that will explore a vast but invisible magnetic
ocean that surrounds our Earth.  This mysterious region we know as
the magnetic field holds off a million mile-per-hour solar wind,
and it's where million-amp electric currents surge and ignite a
show seen as the northern and southern lights.  Lift-off for the
second Cluster duo, named Rumba and Tango, is scheduled for 7:13
a.m. EDT on Wednesday, Aug. 9, aboard a Russian Soyuz rocket from
Baikonour, Kazakhstan.

HUBBLE DISCOVERS MISSING PIECES OF COMET LINEAR

     To the surprise and delight of astronomers, NASA's Hubble
Space Telescope has discovered a small armada of "mini-comets"
left behind by what some astronomers had assumed was a total
disintegration of the explosive comet LINEAR.  Hubble's powerful
vision has settled the fate of the mysteriously-vanished  solid
nucleus of the comet, which seemed to disappear after it moved
around the Sun.
